jsut spend the money on electric fans... - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

JDMClifford · 02-17-2007, 08:28 PM

yep so a week abo ago i broke my clutch fan, and it cut a hose. and today i broke my fuckin waterpump! broke clean off! so now i had to spend almost 200 bucks to get a water pump and aftermarket pulleys... ohh and a fan relay. sooo, chuck the clutch an and get electrick ones, just my 2 cents.

redsuns3838 · 02-17-2007, 08:46 PM

clutch fan has been proven time and time again to cool better and be more reliable than electric fans in daily driving.

sky53line · 02-17-2007, 08:55 PM

Yep. With my clutch fan, my temp gauge never rises. It looks like the car is still off. never rises about 1/2 when drifting.

Well thats not good. You want your car to warm up to operating temp, not stay completely cold... maybe you're thermostat is broken.

About the clutch fan being proven to work better... were the electric fans tested, adequately rated to flow enough air to cool our motors. I'm sure a single 8" or 10" would not be enough. I'm just curious because i was going to invest in electric fans in the near future.

Dutchmalmiss · 02-17-2007, 09:35 PM

Stock fan/shroud ftw. doesn't budge over normal operating temp.

TurDz · 02-17-2007, 09:51 PM

The temperature gauge is one of the worst ways to determine your car's temperature. Just because it stays constant doesn't mean there isn't large temperature fluctuation.

CKAMC · 02-17-2007, 10:05 PM

Someone mentioned Hydro pump to me the other day... my google search terms seem not to help me but supposedly its a mix between electric and clutch or what is it?

I agree about the gauge... factory unit = complete shit

just tap the top rad hose and put a temp sensor there....then an aftermarket guage and then you will have an accurate idea of what the temps really are... after you calibrate the guage of course

C. Senor · 02-17-2007, 11:45 PM

yeah i've personally been told that the clutch fan works great, i went with a koyo and can no longer use clutch fan, so i went electric, i'm using the taurus fan, and works great. i can drive spiritedly with the ac on and then just sit at a light and the car doesnt over heat, but keep in mind i changed radiator, all hoses, thermostat, and water pump. but i wil say i have no problems with electric fan, taurus fan works really good....but that's just me.

corey240 · 02-18-2007, 03:26 AM

my car had dual 12" flex-a-lites and it has not once over heated even when racing, we thought the thermostat was broke so we got a new one and had an after market temp gauge for a couple months befor my rod knock was noticed and it never over heated

blitz180 · 02-18-2007, 04:13 AM

After fucking around with a crappy 12" autozone electric fan, I opted to go with an electric fan out of a 3.8l Ford Taurus. It has a shroud, looks stock and flows high cfm. forgot the exact number, but was above the FAL kit most people get. 25$ at the junkyard.... can't beat value for the buck.

Cloud9 · 02-18-2007, 06:50 AM

Here is some good info on fans http://home.satx.rr.com/nissanweb/RadTest/RadTest.htm

kouki_s14 · 02-18-2007, 12:49 PM

thats not too bad, it happened to my friends bmw twice. clutch fan locked up and shattered, cutting into everything up, including his radiator and put a dent in his hood, TWICE

I cant recall, ive seen quite a few tests. Search around FreshAlloy i know theres atleast 1 test thats been done. I want to say it was dual fans being tested.

KiDyNomiTe · 02-18-2007, 01:24 PM

Ive known people to overheat with fan and shroud, ive known people to overheat with electric fans. They both are good setups, good arguments on both sides.

FAL makes a new kit for 240s, has a bigger shroud and better mounting brackets

sideview_180sx · 02-18-2007, 02:23 PM

that link with the rad test and the link that kidynomite posted both state that ducting is the main catalyst in regards to cooling performance. Regardless if you go back to clutch or bump over to electric. Ducting will be the key that makes of brakes your cooling system.

punxva · 02-18-2007, 03:26 PM

here's what i'm running...

A single Perma-Cool 12" electric fan, wired into my cig. lighter so it turns on when the key is turned to the on postition and off when taken out. No shroud atm though. I'm also running a nismo thermostat, and nismo rad. cap, plus a 60/40 water to coolant, with redline water wetter. Although i currently do not have an aftermarket water temp gauge, i've never overheated, even sitting in 100* weather in bumper to bumper traffic for 2 hours.

Also something i learned, most of those switches and fan thermostats tend to go out, ive gone through 3 before i just decided to wire it in to the cig. lighter

yea those fan thermo suck ass, dont even bother with them. It's gonna go out one day and your fans will shut off, then you overheat. Best option if you dont want your fans on all the time is to get a fan controller from HKS or something.

240sx2jz · 02-18-2007, 04:13 PM

i ran the dual flex-a-lites for a while on my setup (2jz) with the koyo and never had any problems. now im running dual 12" perma cools.....those things friggin rock, i would advise people towards those. even if you gotta make a custom shroud and run dual tens it worth it if you really need some cooling on a high strung motor.

Wei240 · 02-18-2007, 05:47 PM

stock clutch fan AND shroud for the win,
don't know why some people don't run it with the shroud, it's a must

odd, my koyo fits fine using the clutch fan and shroud although it is a tight fit. oh and i haven't overheated in traffic or at the track.

Jefferson · 02-18-2007, 06:43 PM

Never seemed to have a problem with my stock clutch fan so I never bothered to change it, But then again I still have my piece of crap stock temp gauge

kaotic · 02-18-2007, 07:28 PM

I had the same problems when I ditched my e fans and put in the clutch fan.. my water pump broke in two... then, I found out that you HAVE to torq the bolts on the water pump to FSM specs.. otherwise I guess it blows up?

right now im running a stock clutch fan and shourd, vented hood, griffin radiator, and a pusher fan up front.. never have any heat issues.. even when its 110+ outside

how is your car supposed to run hot if its got a cold thermostat? of course its not going to get hot, its always COLD.

am i reading this right, you wired up your electric fan setup through your cigarette lighter? readup a bit about wiring, you need amperage and that cigarette lighter socket is the last place you want to tap power from. install a relay and have it activate via ON 12v signal.

jeeeeeeeeez.

bullshit. clutch fan works but its far from efficient and is not more reliable.

both are good, but clutch fan is useless w/o shroud - i dont know why people dont install the shroud.

IMO, electric fans make the most efficient setups.

hey Kid,

got a ballpark figure as to what those fans go for? i would assume they are made to fit aftermarket rads like koyo?

jeeeeeeeeez.

I remembered that i wired it up a specific way, after i get out of class i'll go out to my car and check exactually how i wired it. I did it the right way, it was just so long ago that i dont remember

MadScientist · 02-19-2007, 11:52 AM

FAL - 345 Dual Electric for 240SX looks like most places are charging about $330ish. It more than the 220 series that most have but this is more specific to the 240SX needs and has an adjustable & manual Thermo switch.

Been seeing alot of people asking about better cooling parts lately.
Its simple to upgrade the components of the Cooling system, and even if you get top of the line everything... your looking at a little over a grand... most people spend more then that on their Turbo alone!!

Samco Hoses - $90-100
Nismo Thermostat - $70-80
New Water Pump - $80
Water Pump Pully - $90-180
FAL Fans - $220-330
Radiator - $300-600

Peace
Drew

punxva · 02-19-2007, 02:22 PM

ok went out and looked at mine, in between my fan and the lighter, i have a 30amp fuse so just wire it like that if you want...

BTW Drew what about us KA's all we have that is comparable to the samco's are the Agency Power hoses...

So you put a huge fuse on those tiny ass cig lighter wires... 18Ga + 30A = hot ass wires. And you'll never know if one of those wires burns up and your fan doesn't come on until it's probably too late. I agree with Mike, do it right, wire up with decent size primary wire (14Ga is cheap), a relay and just tap the +12V ACC or IGN leads to switch your relay.

And on topic - I run a cheap aluminum radiator (think ebay quality) with a single 10" fan from a BMW 318, and ducting, with no clutch fan or shroud ATM. As long as your fan setup can cool you down from any temp at a standstill, it's adequate. Its the ducting and your radiator that determine your cooling ability at speed.

Oh, and don't rely on anything the stock temp gauge tells you... it doens't start moving upwards until about 220*, and doesn't get into the hot until about 245*. I use Autometer liquid filled gauges, supposedly the most accurate, I like em, but just get yourself a good aftermarket gauge.

punxva · 02-19-2007, 03:41 PM

ohh i wired it all the way to the source with 14G, and it's been fine for about 2 years now
